Drillship

A drillship is a merchant vessel designed for use in exploratory offshore drilling of new oil and gas wells or for scientific drilling purposes. In most recent years the vessels are used in deepwater and ultra-deepwater applications, equipped with the latest and most advanced dynamic positioning systems.

History

The first drillship was the CUSS I, designed by Robert F. Bauer of Global Marine in 1955. The CUSS I had drilled in 400 feet deep waters by 1957.
Robert F. Bauer became the first president of the Global Marine in 1958.

In 1961 Global Marine started a new drillship era. They ordered several self-propelled drillships each with a rated centerline drilling of 20,000 foot-wells in water depths of 600 feet. The first was named CUSS (Glomar) II, a 5,500-deadweight-ton vessel, Costing around $4.5 million. Built by a Gulf Coast shipyard, the vessel was almost twice the size of the CUSS I, and became the world’s first drillship built as new construction which set sail in 1962.

In 1962 The Offshore Company elected to build a new type of drillship, larger than that of the Glomar class. This new drillships would feature a first ever anchor mooring array based on a unique turret system. The vessel was named Discoverer I. The Discoverer I had no main propulsion engines, meaning they needed to be towed out to the drill site.
